N 2 Adsorption/Desorption Relationship to Permeability Can we relate pore structural parameters to permeability (dominant pore size, BET surface area?) Currently gathering permeability/porosity data for Cardium so plot like the one on the right (Montney TG) can be developed From Clarkson et al. AAPG Bulletin, in press 26

SANS/USANS In a SANS experiment, a neutron beam is directed at a sample, and the neutrons are elastically scattered due to their interaction with nuclei of atoms in the sample The scattering vector is related to a characteristic length scale (pore size) in the sample SANS experiments, combined with USANS, also enable a wide distribution of pore sizes (~ 0.3 nm to ~ 10 μm) to be investigated From Melnichenko et al.
